Respiratory System Quiz

Which anatomical plane divides the body into front and back halves?

• Sagittal plane

• Transverse plane

• Frontal (coronal) plane

• Oblique plane

Answer explanation

The frontal (coronal) plane divides the body into front and back halves, you are creating a FRONT (FRONTAL) and a back.

The sagittal plane cuts the body in half but through the midline creating a right and left.

The transverse cuts through the mid section creating a top half and bottom half. The TRANSVERSE abdominals is in the area this plane dissects.

Oblique planes dissect diagonally and are NOT on your course syllabus - ignore.

Which of the following exercises occur in the sagittal plane?

• Side leg lifts

• Jumping jacks

• Forward lunge

• Lateral raises

Answer explanation

To understand view an image on google. The plane is like a mirror passing through the body, in this case the Sagittal. Imagine striding forward and performing a forward lunge. The legs would move either side of the imaginary mirror, never crossing it.

Therefore, moving in the sagittal plane.

Which of the following is a function of the skeleton?

• Digestion

• Movement

• Respiration

• Excretion

Answer explanation

If you are here you rushed your answer! None of the others answers are even close.

The function of the skeleton is primarily for movement, providing support and structure for muscles to attach to and facilitate movement.

Which term refers to the horizontal plane of the body that divides the body into upper and lower parts?

• Sagittal

• Coronal

• Transverse

• Oblique

Answer explanation

The transverse cuts through the mid section creating a top half and bottom half. The TRANSVERSE abdominals is in the area this plane dissects.

The frontal (coronal) plane divides the body into front and back halves, you are creating a FRONT (FRONTAL) and a back.

The sagittal plane cuts the body in half but through the midline creating a right and left.

Oblique planes dissect diagonally and are NOT on your course syllabus - ignore.

Which of the following is NOT a structure of the axial skeleton?

• Cranium

• Scapula

• Sternum

• Ribs

Answer explanation

The scapula is part of the Appendicular skeleton. It is made of many bones, most of which are away from the middle of the body.

The Axial skeleton consists of the cranium, sternum, ribs, spine.

Which of the following terms refers to the location closer to the midline of the body?

• Lateral

• Medial

• Distal

• Proximal

Answer explanation

Medial - towards the midline.

Lateral - away from the midline.

Proximal – towards the origin of a limb.

Distal – away from the origin of a limb

Which of the following is a structure of the appendicular skeleton?

• Cranium

• Sternum

• Clavicle

• Ribs

Which of the following is a function of the skeleton related to blood?

• Storage of calcium

• Production of red and white blood cells

• Protection of vital organs

• Movement

Which of the following bones is classified as a long bone?

• Carpal

• Femur

• Patella

• Tarsal

Answer explanation

The femur is classified as a long bone due to its elongated shape and role in supporting the body's weight.

Carpal, and tarsal bones are classified as short bones.

Patella is a flat bone or a short bone.

What is the term for the growth plates found in long bones?

• Epiphysis

• Diaphysis

• Periosteum

• Epiphyseal plates

Answer explanation

The term for the growth plates found in long bones is Epiphyseal plates, which are responsible for longitudinal bone growth.

Periosteum is the sheath that surrounds the bone.

Epiphysis is the END of the bone (words with E&E).

Diaphysis is the shaft.
